Radio In 1895, Tesla began experimentally monitoring the radio emissions of his high-frequency generators, first picking up signals around New York City and later 30 miles up the Hudson River. Though Marconi was given credit for inventing radio, the US Supreme Court later recognized (though not until 1943) Tesla's patent as having priority over Marconi's.

John Logie Baird, the father of this pervasive technology, first publicly demonstrated television on 26 January 1926, in his small laboratory in the Soho district of London.
Television came into being based on the inventions and discoveries of many men and scientists. The 'first' generation of television sets were not entirely electronic. The display (TV screen) had a small motor with a spinning disc and a neon lamp, which worked together to give a blurry reddish-orange picture about half the size of a business card!
